(PL V, figs. 9a— yb; PI. VI, figs. la— ic.) 



Female (without marsupium). Kody slender, a little nu)re than seven times as long as broad, 

 seen from above nearly cylindrical (fig. la). — Carapace as long as or a little shorter than the two 

 following segments combined, not fully half as long again as broad: its lateral margins are nearlv 

 parallel from the base to near the beginning of their distal third, where they begin to converge more 

 distinctly; the anterior end is scarcely more than half as broad as the base and the rostral process is 

 middle-sized, acute. 



Antennulte considerably shorter than the carapace (fig. ic), somewhat slender. First joint, seen 

 from the side, about or not fully three times as long as deep and tapering somewhat irregularly from 

 somewhat from the base to the end; seen from above the joint (fig. i b) is nearly three times as long 

 as broad and tapers nearly regularly; the joint is somewhat or considerabh' longer than the two other 

 ioiuts combined. Second joint from a little less to a little more than half as long as the third and 

 at most about twice as long as deep; longest terminal sette distinctly longer than third joint. — An- 

 tenuje of normal length (fig. ic); third joint somewhat thickened; fourth joint at most half as long 

 again as the penultimate; terminal seta; about as long as those of the antennulte. 



Chelipeds (fig. ic) somewhat long but onh' moderately robust. The basal joint somewhat long, 

 its posterior process large, a little longer than deep with its rounded hind margin considerably distant 

 from the front margin of second thoracic segment; carpus considerably longer than the basal joint, 

 three and a half times as long as deep. Chela a little shorter than the carpus, a little less than four 

 times as long as broad; movable finger a little shorter than the front margin of the hand; fixed finger 

 at the base somewhat thicker than the movable. 



Thoracic segments with the lateral margins parallel excepting on second and seventh seg- 

 ments, on which the margins converge feebly respectively from the front angles backwards and from 

 behind forwards. Second segment about two-thirds as long as the third, without ventral process; fifth 

 segment a little longer than the fourth or the si.xth and scarcely as long as broad. Thoracic legs 



moderately strong. vSecond pair (fig. ic) quite peculiar; fourth joint \ery elongate, about two and a 

 half times as long as the fifth; sixth joint slightly more than half as long again as the fifth; seventh 

 joint with claw as long as the fifth; set;e .short. Third pair nornml; fourth ami fifth joints subequal 

 in length; sixth joint about half as long again as the fifth and nune than twice as long as the 

 seventh with claw; the sets moderately short excepting a .somewhat long, distal seta from the side 

 of sixth joint. Three posterior pairs not very characteristic; secoiul joint (fig. gal about two and a 

 half times as long as broad; fourth joint with a minute distal tooth; fifth joint slightly broader than 

 the fourth, with one of the margins somewhat convex but without anv distinct armature; sixth joint 

 moderately or rather .slender, almost as Icnig as the two jireceding joints combined, with a minute 

 spine .somewhat before the end; seventh joint with claw of middle length. 



Abdomen slightly broader than the posterior thoracic segments and scarcely as long as tlie
